Some time ago, IPv4 filtering blocks longer than /20 was fairly common. In fact, when ARIN passed 2002-3 (its micro-assignment policy for multi-homed networks), that was still the case. While there was not a land-rush to claim smaller blocks, there was adoption even though the recipients had to deal with this, and over time it all seems to have sorted itself out adequately.
The /20 filtering mentioned was probably for ARIN blocks then, because it wasn't a general practice as I've experience with /24 in RIPE space since 1995-1996 or so and it wasn't a problem back then and is not now. -- Mikael Abrahamsson email: swmike@swm.pp.se
